try cleaning the inside of your computer. But dont get scared when you fine piles and piles of dust, but cleaning the inside of your computer helps a lot! And I mena everything. The fan(s), power supply (as much as possible (try using earpicks), bottome of your computer, and ALSO DONT FORGET TO CLEAN THIS PLACE IT HAS THE MOST FILTH, the front of teh computer where the usb's are except on the inside of teh computer, near the usb's on the front there is so much filth.
